Piecewise Circlular Curve Applet
DIRECTIONS: In this applet, you create a smooth piecewise
circular curve by specifying a sequence of points. The first two
points determine a oriented tangent line at the second point.
Then a circular arc is created from the oriented tangent line
and the next point that interpolates the second and third point.
The circular arc defines an oriented tangent line at the third
point, so each subsequent point placed creates a new circular
arc.
